This is a summary of Talk2Me in the ISLAND Cohort Study (n=1823). This is a collaboration led by Dr Eddy Hill (University of Tasmania) and Prof Frank Rudzicz (University of Toronto) to explore the associations between features extracted from Talk2Me, with covariates including age, gender, education, background health and cognition (CANTAB).
Data was requested from ISLAND’s data administrators, Tim Saunder and Alex Kitsos. 1823 participants completed the updated Background survey, with 1447 completing the updated survey multiple times. Data were collected between 2019 and 2020, with any participants included that completed the Background Health and Background Update survey for any timepoint since October 2019.
We predominantly selected Background & Health Update data for ISLAND’s October 2020 timepoint, as all 1823 Talk2Me participants had completed this task, and this contains the most recent information. After merging ISLAND Background & Health Update with CANTAB IDs, we can see that 1432 ISLAND participants who completed Talk2Me have a CANTAB ID (391 were NAs). For the purposes of this study, we have selected some variables from Background Health (October 2019) and Background Health Update (October 2020). Details of which variables were selected are found in the data dictionary tab.

A summary of variables included in the CANTAB output. Norms calculated from CANTAB’s own battery, dependent on age and education.
Please note to merge ISLAND_CANTAB with Tal2Me, the following ID codes shall be used island_cantab(user_id) = auth_user(mm2_user_id)
Further, auth_user(id) from 1018 to 1040 should be omitted as these are tests conducted by ISLAND staff members

| SWM Recommended Standard 2.0 Extended | SWMDE468 | SWM Double Errors: The number of times a subject commits an error that is both a within error and a between error. Calculated across all assessed four, six and eight token trials. |
| SWM Recommended Standard 2.0 Extended | SWMDE6 | SWM Double errors 6 boxes: The number of times a subject commits an error that is both a within error and a between error. Calculated across all trials with 6 tokens only. |

| SWM Recommended Standard 2.0 Extended | SWMPR | SWM Problem Reached: This measure reports the problem number that the subject reached, but did not necessarily complete. |
| SWM Recommended Standard 2.0 Extended | SWMS | KEY: SWM Strategy (6-8 boxes): The number of times a subject begins a new search pattern from the same box they started with previously. If they always begin a search from the same starting point we infer that the subject is employing a planned strategy for finding the tokens. Therefore a low score indicates high strategy use (1 = they always begin the search from the same box), a high score indicates that they are beginning their searches from many different boxes. Calculated across assessed trials with 6 tokens or 8 tokens. |
| SWM Recommended Standard 2.0 Extended | SWMS6 | SWM Strategy (6 box only): This measure computes the strategy score for the 6 box stage of the task only. The strategy score is calculated based on the number of times a subject begins a new search pattern from the same box they started with previously. If they always begin a search from the same starting point we infer that the subject is employing a planned strategy for finding the tokens. Therefore a low score indicates high strategy use (1 = they always begin the search from the same box), a high score indicates that they are beginning their searches from many different boxes. |
| SWM Recommended Standard 2.0 Extended | SWMSX | SWM Strategy (6-12 boxes): The number of times a subject begins a new search pattern from the same box they started with previously. If they always begin a search from the same starting point we infer that the subject is employing a planned strategy for finding the tokens. Therefore a low score indicates high strategy use (1 = they always begin the search from the same box), a high score indicates that they are beginning their searches from many different boxes. Calculated across assessed trials with 6 tokens or more. |
| SWM Recommended Standard 2.0 Extended | SWMTE12 | SWM Total errors 12 boxes: The number of times a box is selected that is certain not to contain a token and therefore should not have been visited by the subject, i.e. between errors + within errors - double errors. Calculated across all trials with 12 tokens only. |
